Concrete pump and method for supporting a concrete pump
The invention relates to a concrete pump, comprising: —a frame; —a supporting leg, the supporting leg having a supporting foot, the supporting foot being extensible relative to the supporting leg; and —a drive for driving a movement of the supporting leg relative to the frame. A camera image of a hazard zone around the supporting leg is produced by a monitoring sensor. The drive is controlled by means of a remote control. The data information is transferred to the remote control via an interface. The invention also relates to a method for supporting a concrete pump. On the basis of the received data information, it can be determined, by means of the remote control, whether the movement of the supporting leg causes a hazard.
1. A concrete pump comprising:
a frame;
a supporting leg connected to the frame, the supporting leg comprising a supporting foot deployable relative to the supporting leg;
a drive for driving a movement of the supporting leg relative to the frame;
at least one monitoring sensor mounted to a distal section of the supporting leg and configured to obtain data information relating to a hazard region of the supporting leg;
a remote control for actuating the drive, said remote control usable at different locations relative to the concrete pump; and
an interface for transmitting the data information to the remote control,
wherein the data information relating to the hazard region of the supporting leg is transmitted to the remote control, allowing an operator of the concrete pump at the remote control to decide whether danger will be caused by movement of the supporting leg between a retracted state and a deployed state.
2. The concrete pump of claim 1 , wherein the remote control is equipped with an indicator unit for indicating the data information received.
3. The concrete pump of claim 1 , wherein the at least one monitoring sensor comprises monitoring sensors connected to the frame or to a boom of the concrete pump.
4. The concrete pump of claim 1 , wherein the at least one monitoring sensor comprises a plurality of monitoring sensors.
5. The concrete pump of claim 1 , wherein the remote control is formed as a portable operating unit.
6. The concrete pump of claim 1 , wherein the remote control comprises an operating element with which a movement of the supporting leg is actuated.
7. The concrete pump of claim 1 , wherein said at least one monitoring sensor includes a camera and an image from the camera is transmitted to the remote control via the interface.
8. The concrete pump of claim 7 , wherein the remote control comprises a display for indicating the camera image.
9. The concrete pump of claim 8 , wherein the display is subdivided so that camera images of a multiplicity of cameras can be represented simultaneously.
10. The concrete pump of claim 8 , wherein the remote control is configured to represent camera images of a multiplicity of cameras in a chronological sequence.
11. The concrete pump of claim 1 , wherein the interface to the remote control is embodied as a wireless interface.
12. The concrete pump of claim 1 , wherein the monitoring sensor comprises a collision sensor, a movement of the supporting leg being automatically brought to a stop if the collision sensor determines an impending collision.
13. The concrete pump of claim 11 , wherein the remote control is configured according to a single operator input, both to move the supporting leg relative to the frame and to move the supporting foot relative to the supporting leg.
14. The concrete pump of claim 1 , comprising:
a boom mounted to the frame and rotatable relative to the frame about a vertical axis,
wherein movement of the supporting leg relative to the frame includes deployment of the supporting leg with a swiveling movement or with a linear movement, a horizontal distance between the vertical axis and the supporting foot increasing when the supporting leg is deployed.
15. The concrete pump of claim 1 , wherein the monitoring sensor is a contactless monitoring sensor selected from the group comprising a camera for the image visible to a person, a RADAR sensor, a LIDAR sensor, an infrared camera, and an ultrasound sensor.
16. A method for supporting a concrete pump comprising a supporting leg moveable relative to a frame of the concrete pump between a retracted position and a deployed state by a drive, said supporting leg having a supporting foot deployable relative to the supporting leg, said method comprising:
mounting a monitoring sensor to the supporting leg so that a relative position of the monitoring sensor and the supporting leg does not change during movement of the supporting leg;
monitoring a hazard region of the supporting leg using the monitoring sensor to collect data information relating to a hazard condition in one or more movement directions of the supporting leg;
transmitting information relating to the hazard condition to a remote control configured as a portable operating unit from which the drive of the supporting leg can be actuated;
configuring the remote control to comprise an indicator device indicating the data information from the hazard region of the supporting leg; and
allowing actuation of the drive by a user of the remote control only if the indicator device is actively indicating the data information from the hazard region of the supporting leg.
17. The method of claim 16 , comprising:
evaluating the data information from the monitoring sensor to determine derived data information more readily comprehensible to the user than direct measurements of the monitoring sensor.
18. The method of claim 17 , wherein the derived data information is a statement whether or not a hazard situation exists in the hazard region of the supporting leg.
